Hyperhidrosis refers to abnormal excessive sweating either locally or over the entire skin surface that occurs under normal living conditions or circumstances. In Western medicine, hyperhidrosis is primarily attributed to psychological factors, hemiplegia, concussion, and other causes of autonomic nervous damage or dysfunction, as well as some endocrine disorders, such as hyperthyroidism and diabetes. Sometimes, it can also be a symptom accompanying other diseases. The occurrence of hyperhidrosis is linked to an increase in sympathetic nerve impulses that enhance the excitement of sweat glands, leading to excessive sweating. It can also be due to increased nervous tension in the sweat glands, which intensifies the sweating response. Furthermore, excessive sweating can occur with the extensive use of corticosteroids, and it can be categorized into localized sweating and generalized sweating. According to traditional Chinese medicine, there are two types of excessive sweating: spontaneous sweating and night sweating. Spontaneous sweating entails sweating during the day without much physical activity, which worsens with exercise and is associated with qi deficiency. Night sweating occurs during the night and is accompanied by symptoms such as warmth in the palms and soles and irritability, indicating yin deficiency.
